So what Turbo do you guys think i should use for this setup to get the best response i want everyones expert advice and why that turbo the more info the better
after going through your list, im not entirely sure you know exactly what you are wanting to do/getting yourself into.
first off, why a d15b block? sure its fun to be JDM and all, but the nothing of the D15 and D16 interchange in the bottom end and should something fail or you need something internally, you will be down for a while. Save yourself the headache and start with a Z6 at the bare min if you want to go vtec but if not, a stout A6 bottom end will get you the numbers you want.
your bottom end parts list looks fine except the steel crank pulley and block guard. Your are gonna spend the money to build a bottom end and get a rotating assembly put together only to piss that money away by purchasing a steel crank pulley and wiping out your bearings and or oil pressure? There is a reason honda motors (after 92) came factory with harmonic balancer. Save yourself the agony and grief and money and get a bottom end put together with a balancer and not those stupid ass POS pullies. You will thank me later.
Block guards are a no-no. They are a band-aid to the floating honda sleeve problem. If you want cooling system nightmares and constant over heating probs, be my guest but i dont know of a local motor that hasnt had issues with a bottom that had a block guard. Stock honda sleeves will take a shit kicking to 500whp (LS blocks) where as a D-series wont have issues if all you want is 300whp. We were hitting the 280whp mark with stock sleeves at our big june dyno day on a similar setup to yours but in a Z6 varient.
Your head pieces for the most part seem fine. Im confused though. you are getting "Skunk2 high compression oversized valves?" So you are gonna spend the money to get a head built but then put in chinese offshore valves in it? Again save yourself the headache, send the head down to bisi, especially if you are already getting a bunch of shit from him anyway and get it done right the first time. Oh and for future reference, stay away from S2 stuff. nothing but headaches. valvetrain parts id look at ferrea or supertech valve train. reliable and at least you know its made in the states and made right.
intake manifold go with a blox if you really want a s2. at least the blox fits in the engine bay half ass alright, way better than a S2, either that or go with a large plenum edelbrock victor X, the are a much nice unit and only a couple of bux more. oh and you dont need a fancy throttle body unless you like pissing away money. A H22 or even a B16 or B18c will do the job just nicely. 300whp is a measly goal and if thats all you want, you dont need to go balls out. stock Z6 motors on a solid tune can push well over 400whp easily.
"Cooling: Mishimoto Aluminum rad
custom I-C piping 2.5 inchs"
that just sounds like you pulled a line out of fast and the furious.
keep it simple rock star. A koyo or yonaka aluminum core rad will be just fine and a decent bar and plate front mount. If you feel the need to impress, a spearco cored intercooler or even a PWR and a fluidyne will suffice.
take this as advice, not a dig. ive been doing this stuff for a while.
edit: fuck chris harris and xenocron.com. he screwed the entire homemadeturbo crowd. we supported him when he bought the site and fucked us in the end for the almighty buck. Dont support that greddy money hungry fuck. that is all
